Does anyone know if there is a limit to the number of Skyline ($1) tickets that someone can buy on the day of the game?  Also, do these tickets go on sale when the box office opens first thing in the morning or is it when the gates open?

I've looked all over and I've read a lot of different things - such as one Skyline ticket per person and that the tickets go on sale one hour before the game or when the gates open.  I'd like to go buy the tickets first thing in the morning for me and some friends and then come back around game time and enter.
